CLEAN CITIES ALTERNATIVE FUEL PRICE REPORT JULY 2019

2

Welcome to the July 2019 Issue!The Clean Cities Alternative Fuel Price Report (AFPR) is a quarterly report designed to keep Clean Cities coalitions and other interested parties up to date on the prices of alternative and conventional fuels in the United States. This issue summarizes prices that were submitted between July 1 and July 15, 2019, by Clean Cities coordinators, fuel providers, and other Clean Cities stakeholders.

What’s New in This Issue:For the July 2019 report, 4,661 prices were submitted, a slight increase from April 2019’s 4,640 prices. This included 287 prices for lesser-used fuels such as ethanol blends between E15 and E50, biodiesel blends such as B5, B10, and B50, hydrogen, and renewable diesel. A total of 32 renewable diesel prices were submitted by 5 coalitions in California. The data submitted for the lesser-used fuels is maintained in the database for possible future use; we do not currently include separate sections addressing those fuels in this publication, due to an insufficient number of data points.

In the July report, the national average retail price of gasoline held steady, while the national average retail price of diesel decreased slightly, by $0.05/gallon, when compared to April 2019.

The national average retail prices of E85, liquefied natural gas (LNG) and B99/B100 increased slightly, by $0.05/gallon, $0.08/diesel gallon equivalent (DGE), and $0.11/gallon, respectively, when compared to April 2019. The national average retail prices of compressed natural gas (CNG), biodiesel (B20), and propane decreased slightly, by $0.01/gasoline gallon equivalent (GGE), $0.02/gallon, and $0.07/gallon, respectively.

CNG prices continued to be lower than gasoline in all regions during this period, with a national average retail price difference of $0.55/GGE. The price difference was largest in the West Coast region, where CNG was $1.05/GGE less than gasoline. CNG also remained less expensive than diesel in all regions, with a national average retail price difference of $0.54/DGE. The price differences ranged from $0.13/DGE less in the New England region to $0.99/DGE less in the West Coast region. Similarly, LNG was less expensive than diesel by a national average of $0.28/DGE, with the largest difference in the West Coast region, where LNG was $1.10/DGE less than diesel.

Looking AheadWe will continue to improve the Alternative Fuel Price Report, based on user feedback. We look forward to hearing from you as we implement these upgrades. See page 27 for contact information.

CLEAN CITIES ALTERNATIVE FUEL PRICE REPORT JULY 2019

Methodology• This report’s prices represent retail, at-the-pump sales

prices for each fuel, including federal and state motor fuel taxes.1

• Clean Cities coordinators, fuel providers, and other key stakeholders provide prices for fuels in their areas on a voluntary basis.

• Prices were submitted for all major alternative fuels currently in widespread use, i.e., natural gas, propane, biodiesel, and ethanol.

• Prices were submitted for conventional fuels from stations that also sell alternative fuels, or from nearby stations.

• Prices from public and private refueling stations are included.2

• Prices were averaged to determine regional price trends by fuel and variability in fuel price within and among regions.3

• Some states charge a flat annual fee in lieu of collecting motor fuel taxes at the pump, usually for large trucks using gaseous fuels like compressed natural gas (CNG) and liquefied petroleum gas (LPG or propane). These flat fees are not included in the prices reported in these pages.

• Consistent with the U.S. Energy Information Administration (EIA) fuel price reporting format, prices are grouped by the Petroleum Administration for Defense Districts (PADD). The PADD districts are illustrated in the map below.

1 In some cases, prices were submitted by government refueling facilities, and motor fuel taxes were not included in the prices reported to Clean Cities. In these instanc-es, the appropriate federal and state motor fuel taxes have been added to the reported prices to provide a more representative basis for comparison. 2 Public refueling stations are open to the public, while private fueling stations are privately owned or available only to selected fleets. 3 Fuel price averages for this report are determined by simply averaging the individual data points received. A comparison of average fuel prices for private and for public stations by region can be found on pages 22–23.

Summary of Current Report Information

Liquid fuels have differing energy contents per gallon, so the price paid per unit of energy content can differ somewhat from the price paid per gallon. Table 3 shows fuel prices from Table 2 normalized to an energy-equivalent basis.

Note that, for the alternative fuels, prices on an energy-equivalent basis, i.e., $/GGE or $/DGE, are generally higher than the prices per gallon, due to their lower energy content.5

Propane prices include information from both “primary” and “secondary” stations. Primary stations have dedicated vehicle services and tend to be less expensive than secondary stations, which mostly serve the propane tank and bottle market.

Prices for Table 3 were calculated using the nominal lower heating values in British thermal units (Btus) per gallon of fuel from Appendix B of the Oak Ridge National Laboratory’s Transportation Energy Data Book.6

Table 2 shows national average retail fuel prices for this report and the previous report.4

Changes in average retail prices from one quarter to another may be due to a number of factors, including an actual change in price, different sample sizes, the inclusion of different locations, and seasonal variations in demand.

Prices in this report were reported in the units in which they are typically sold, for example, dollars per gallon of gasoline or dollars per gasoline gallon equivalent (GGE) of CNG.

Consumer interest in alternative fuels generally increases when the alternative fuel price is less than the conventional fuel price on a per gallon basis, even if that differential does not directly translate to savings on an energy-equivalent basis.

4 A very small sample (13 points) of hydrogen information was received, with an average price of $15.95/GGE. 5 For ethanol flexible-fuel vehicles (FFVs), the actual difference in fuel used per mile is somewhat less than would be calculated simply on the difference in energy content of the fuels. Some sources have noted that some FFVs can achieve better energy efficiency (miles per unit of energy) on E85 than on gasoline. This effect is not currently included in these calculations as the magnitude of the effect varies by specific FFV model.6 https://tedb.ornl.gov/. A listing of the conversion factors used appears in Illustration of Conversion Factors for Fuels on page 25.

CLEAN CITIES ALTERNATIVE FUEL PRICE REPORT JULY 2019

Gasoline and Diesel Prices: Clean Cities and EIA Data

Table 4 shows gasoline and diesel prices submitted by Clean Cities coordinators, fuel providers, and other stakeholders on a voluntary basis between July 1 and July 15, 2019, compared to prices from the petroleum information section of the Energy Information Administration (EIA) website for the week of July 8, 2019.

Clean Cities prices for conventional fuels were obtained from retail stations providing alternative fuel price information, or from nearby stations, so data collection was not uniform across the regions of the country; however, the information is representative of refueling stations selling both alternative fuels and conventional fuels.

*EIA prices are from the petroleum information section of the EIA website, week of 07/08/2019.http://www.eia.gov/dnav/pet/xls/PET_PRI_GND_A_EPMR_PTE_DPGAL_W.xlshttp://www.eia.gov/dnav/pet/xls/PET_PRI_GND_A_EPD2D_PTE_DPGAL_W.xls**Negative numbers represent average Clean Cities prices that are lower than EIA prices.

The EIA data shows weekly average prices from a sample of approximately 800 retail gasoline and 400 retail diesel outlets across the country. The EIA data points are weighted to reflect the quantity of fuel being sold at that price.

The Clean Cities data is not weighted, and represents simple averages of reported prices. While there is some variation, the EIA average prices match relatively closely with the average prices reported by Clean Cities coordinators.

Compressed Natural Gas (CNG) Relative to Gasoline

CNG prices in Table 5 were obtained from the “price at the pump,” given in $/gasoline gallon equivalent (GGE), and averaged for each region.

As with other fuels, the energy content of natural gas can vary. CNG dispensers are calibrated for local gas compositions and dispense an accurate GGE for the actual gas being sold.

The prices shown in Table 5 were submitted by Clean Cities coordinators, fuel providers, and other stakeholders on a voluntary basis between July 1 and July 15, 2019.

On average, during this reporting period, CNG cost about $0.55 less than gasoline on a per GGE basis.

In this map, negative numbers represent prices for CNG that

are lower than gasoline, on a per gasoline gallon equivalent basis.

States not highlighted with a color did not have any CNG data points in

the current report.

Note: The AFPR is a snapshot in time of retail fuel prices. Alternative fuel fleets can obtain significantly lower fuel prices than those reported in the AFPR by entering into contracts directly with local fuel suppliers. Contract prices will vary, depending on fleet size and amount of fuel to be purchased, distance from the supplier, region of the country, and other factors.

Ethanol (E85) Relative to Gasoline

Most gasoline available throughout the United States today is a blend of 90% gasoline and up to 10% ethanol, or E10. Additionally, the E85 that is sold in the United States today actually contains, on average, approximately 70% ethanol.

E85 energy content for this report is therefore calculated as (.70)(E100 energy content) + (.30)(E0 energy content), to more closely reflect the actual energy content of E85 fuel available today.

The prices shown in Table 8 were submitted by Clean Cities coordinators, fuel providers, and other stakeholders on a voluntary basis between July 1 and July 15, 2019.

On average, during this reporting period, E85 cost about $0.40 less than gasoline on a per (liquid) gallon basis. See page 26 for a $/GGE comparison.

In this map, negative numbers represent prices for E85 that are

lower than gasoline, on a per gallon basis. States not highlighted with a color did not have any E85 data

Propane (LPG) Relative to Gasoline

Propane prices in this report are from both private fleet refueling stations and public refueling sites that can provide propane for vehicles and for other uses.7

On average, during this reporting period, propane cost about $0.07 more than gasoline on a per (liquid) gallon basis. See page 26 for $/GGE.

The prices shown in Table 9 were submitted by Clean Cities coordinators, fuel providers, and other stakeholders on a voluntary basis between July 1 and July 15, 2019.

Note: The AFPR is a snapshot in time of retail fuel prices. Alternative fuel fleets can obtain significantly lower fuel prices than those reported in the AFPR by entering into contracts directly with local fuel suppliers. Contract prices will vary, depending on fleet size and amount of fuel to be purchased, distance from the supplier, region of the country and other factors.

7 Because many propane retailers provide fuel for non-vehicle uses (camping stoves, gas grills, etc.), the National Renewable Energy Laboratory (NREL) has worked with suppliers to clarify the differences. On the Alternative Fuels Data Center Station Locator website (http://www.afdc.energy.gov/locator/stations/) each public propane station is designated as a “primary” or “secondary” service type. Both types are able to fuel vehicles; however, stations designated as “primary” have indicated they have facilities and billing procedures specifically designed for vehicle customers. They may also offer special vehicle pricing and most accept major credit cards, similar to traditional gasoline/diesel retailers. Propane pricing reported here reflects a sampling of both primary and secondary stations.

In this map, negative numbers represent prices for propane that are lower than gasoline, on a per gallon basis. States not highlighted with a

color did not have any propane data points in the current report.

Illustration of Conversion Factors for Fuels

8 https://tedb.ornl.gov/9 According to the National Renewable Energy Laboratory Alternative Fuels Data Center, the energy content of common gasoline baseline references (E0, E10, and indolene) varies between 112,114 and 116,090 Btu/gal. We chose 114,300 Btu/gal for the E10 energy content, consistent with the Transportation Energy Data Book energy content of CNG, in GGEs. See next footnote.10 (5.66 lbs. of CNG/GGE) x (20,200 Btu/lb.) = 114,332; rounded to 114,300.11 Most gasoline available throughout the United States today is a blend of 90% gasoline and up to 10% ethanol, or E10. Additionally, the E85 that is sold in the United States today actually contains, on average, approximately 70% ethanol. E85 energy content for this report is therefore calculated as [(.70) x (E100 energy content)] + [(.30) x (E0 energy content)], to more closely reflect the actual energy content of E85 fuel available today.12 See footnote 11, above.13 In July 2016, at its annual meeting, the National Conference of Weights and Measures voted to approve the diesel gallon equivalent (DGE) as an authorized method of measuring natural gas sold as a vehicle fuel. 1 DGE means 6.059 lbs. of liquefied natural gas (LNG) or 6.384 lbs. of compressed natural gas (CNG).

Fuel Lower Heating Value

Gasoline (E0) 115,400 BTU/gal

Gasoline (E10)9 114,300 BTU/gal

Diesel 128,700 BTU/gal

Biodiesel (B100) 117,100 BTU/gal

Ethanol (E100) 75,700 BTU/gal

Propane 83,500 BTU/gal

TABLE 14 Lower Heating Values

Conversion to GGE

The conversion factor used to convert the price of an alternative fuel from $/gallon to $/GGE is determined as follows:

Conversion factor = BTU/gal of gasoline (E10) BTU/gal of alternative fuel

To calculate the price of an alternative fuel in $/GGE, multiply the price per gallon of the alternative fuel by the relevant conversion factor from Table 15. For example, if the price of B20 is $3.00/gal, the $/GGE is ($3.00/gal) x .90 = $2.70/gal.

Biodiesel (B20) 0.90

Biodiesel (B100) 0.98

CNG 1.00

Propane 1.54

TABLE 16 Conversion Factors: $/gal to $/DGE

Conversion factors used to establish prices in dollars per gasoline gallon equivalent ($/GGE) and dollars per diesel gallon equivalent ($/DGE) were developed using the lower heating values from the Transportation Energy Data Book Edition 37, Table B.4,8 and are listed to the left.

In the case of CNG, prices are provided to us in GGE, so no conversion is necessary. The representative heating value of CNG is provided in Table 14 as a reference.

Conversion to DGE

The conversion factor used to convert the price of an alternative fuel from $/gallon to $/DGE is determined as follows:

Conversion factor = BTU/gal of diesel BTU/gal of alternative fuel

For example, the conversion factor used to convert a B100 price from $/gal to $/DGE is determined as follows:

128,700 BTU/gal of diesel = 1.099, rounded to 1.10 117,100 BTU/gal of B100

To calculate the price of an alternative fuel in $/DGE, multiply the price per gallon of the alternative fuel by the relevant conversion factor from Table 16. For example, if the price of B100 is given as $3.00/gal, the $/DGE is ($3.00/gal) x 1.10 = $3.30/DGE.

Comparison of Prices on an Energy-Equivalent BasisThe following tables compare prices for E85, propane, B20, and B99/B100 to conventional fuels (gasoline and diesel) on an energy-equivalent basis. (Natural gas is generally sold in gasoline gallon equivalents or diesel gallon equivalents, so the natural gas “price at the pump” can be directly compared to the price of the corresponding conventional fuel, as shown in Tables 5, 6, and 7.)

*Negative numbers represent average E85 prices that are lower than gasoline, on a $/GGE basis.

*Negative numbers represent average propane prices that are lower than gasoline, on a $/GGE basis.

*Negative numbers represent average B20 prices that are lower than diesel, on a $/DGE basis.

*Negative numbers represent average B99/B100 prices that are lower than diesel, on a $/DGE basis.
